7. The recording data generating apparatus according to claim 1 , wherein the halftone processing unit generates the quantization data by using a random number generator.
8. The recording data generating apparatus according to claim 1 , wherein the conversion unit performs the conversion by referring to a lookup table describing a correspondence relation between discrete gloss data and the inclined structure data.
9. The recording data generating apparatus according to claim 1 , wherein the gloss data includes data of reflection haze.
10. The recording data generating apparatus according to claim 1 , wherein the gloss data includes data of image clarity.
11. The recording data generating apparatus according to claim 1 , wherein the gloss data is data of a variable reflection characteristic.
12. The recording data generating apparatus according to claim 1 , wherein the gloss data is a parameter of a reflection model.
13. The recording data generating apparatus according to claim 12 , wherein the reflection model is a Ward model.
14.
